Abstract

The invention provides a polishing-free mirror surface type stone-like flexible sheet and a preparation method thereof. The polishing-free mirror surface type stone-like flexible sheet sequentially comprises a polishing-free mirror surface coating, a dry-wet rock sheet layer, a waterproof reinforcing coating and a flexible waterproof cushion layer, and the flexible waterproof cushion layer is a base layer of the polishing-free mirror surface type stone-like flexible sheet; and the polishing-free mirror surface coating, the dry-wet rock sheet layer, the waterproof reinforcing coating form a stone-like facing layer of the polishing-free mirror surface type stone-like flexible sheet. The polishing-free mirror surface type stone-like flexible sheet provided by the invention can replace naturalstone construction on a large scale due to light dead weight, high gloss and good flexibility, and has no danger of high-altitude falling; the stone-like flexible sheet is convenient to cut, and construction seamless splicing can be achieved; meanwhile, due to the excellent flexibility and elasticity, the cracking risk is avoided, and the material can be applied to complex wall construction and can be applied to the surfaces of columns and other arc-shaped walls; the high-gloss stone-imitating effect is good, and the color and texture like those of polished stone are achieved.

Description

technical field [0001] The invention relates to the technical field of building materials, and more specifically relates to a non-polishing mirror-surface imitation stone flexible sheet pasted on the surface of a building wall, and a preparation method of the non-polishing mirror-surface imitation stone flexible sheet. Background technique [0002] As a high-grade building decoration material, natural stone is widely used in indoor and outdoor decoration design, curtain wall decoration and public facilities construction because of its natural pattern, high hardness, wear resistance, good durability and calm and atmospheric decorative effect. However, due to its high cost, excessive self-weight, too large gap when the stone is docked, it is difficult to cut, seamless splicing cannot be achieved, insufficient elasticity, cracks will occur in case of impact, etc., which will easily cause construction difficulties, high-altitude drop and other hazards , and the radioactive subst...
